WebThe plants known as horsetails or scouring rushes belong to the genus Equisetum, the only remaining genus in the phylum Sphenophyta, a group of seedless vascular plants. Members of the phylum Sphenophyta, the horsetails, reached their maximum diversity during the Late Devonian and Carboniferous periods. WebPhotosynthetic organs become leaves, and pipe-like cells or vascular tissues transport water, minerals, and fixed carbon throughout the organism. In seedless vascular plants, the diploid sporophyte is the dominant phase of the lifecycle. The gametophyte is now an inconspicuous, but still independent, organism.
